Bug#989370: general: In bonding network configuration, hwaddress crashes networking service, fails to restart
Package: general
Severity: important
Dear Maintainer,
* What led up to the situation?
Created a network configuration via /etc/network/interfacess file method for a single ethernet NIC,
i.e. eth0, and WiFi adapter, i.e. wlan0. Both had customized MAC addresses via the 'hwaddress' option.
This configuration worked as expected with no issues.
* What exactly did you do (or not do) that was effective (or ineffective)?
Changed the configuration to a bonding configuration adding bond0 interface, and changing the eth0
and wlan0 configuration to work as slaves under a simple active-backup bonding configuration.
* What was the outcome of this action?
On reboot or systemctl restart networking, the networking service fails, and network connectivity is
broken, nonfunctional. ONLY AFTER REMOVING 'hwaddress' option under bond0 interface configuration,
did networking start as expected. Did not expect the 'hwaddress' option to working on slave interfaces,
but it should have worked on the bond, i.e. bond0 interface. Nowhere in the documentation, that I
have found as yet, is the 'hwaddress' feature excluded from a bonding configuration.
* What outcome did you expect instead?
MAC address set per 'hwaddress' option of bond0 interface, at a minimum, set as expected, and networking
being functional. Fail to understand why hwaddress option fails on bond0 interface when bond0 configuration
is functional without said option being used. At a minimum, if eth0 interface as primary has a 'hwaddress'
option set, the bond0 configuration should accept it. But a better implementation would be for the bond0
interface to accept use of the hwaddress option. Which apparently is not the case now.
